-
- Right. There was much speculation about muons and other cosmic rays in
- particular, plus possible novel particles as final products or as part
- of the mechanism.
-
- However, it is not true that all experiments were shielded or that all
- shielded experiments got null results.
-
- There were at least two experiments that I know about that were set up
- with scintillator paddles positioned to provide veto or coincidence
- information on possible fuision neutron events associated with cosmic
- radiation. These did not see any results above background.
-
- There was also a Jones experiment done in a mine near Leadville that
- was below a separate experiment that was looking at very high energy
- cosmic rays. He saw bursts of neutrons (at a level hundreds of times
- weaker than his original paper reported) at very infrequent intervals.
- The timing of these bursts was then checked with events seen at the
- surface experiment and it was noted that there was no correlation.
-
- Note that a silver mine would be expected to have a significant alpha
- background that could be relevant. However, it is very unlikely that
- the alphas could penetrate the apparatus, and the rates Jones saw were
- not a possible explanation for any heat. Ying's suggestion poses an
- interesting question to those who thought they had controlled all the
- variables in the problem....
